Continental and Michelin provided measurement data for free use by the TMPT. The aim of this paper is to describe how these data are experimentally obtained. Then some insight into the data's physical meaning is given. In the last part, it is shown how the effort for gathering these data interferes with the tire development process. Finally, a proposal is made to replace the costly and time-consuming measurement process by a far more adapted simulation process aiming for the satisfaction of both the customers and suppliers.

“…This has usually been calculated according to a predefined convergent objective function in previous research. [13][14][15][16][17][18] Therefore, the potential of the optimization algorithm can be limited because of its convergence characteristic as regards the predefined target. For example, even when the optimization algorithm has a sufficiently high potential to optimize the tyre pitch sequence, if the objective function has already achieved the predefined target, the optimization process must stop.…”

“…The computational load is relatively low in this method and the effects of minor pitch elements on the tyre pitch length can be ignored owing to the limitations of the Fourier transform method; however, this is not true for the groove elements, which are one of the major pattern elements. An image-based analysis method 15 was introduced to predict the tyre air-pumping noise directly by modelling the air pumping in a pixel-based image format. This method makes it possible to consider the effects of the depth and the minor pitch elements in detail with a relatively small amount of computation.…”

The paper presents a novel approach to solving problems involved in the application of a genetic algorithm to determine the optimal tyre pitch sequence to reduce the tyre air-pumping noise which is generated by the repeated compression and expansion of the air cavity between the tyre pitch and the road surface. The genetic algorithm was used to determine the optimal tyre pitch sequence with a low level of tyre air-pumping noise using the image-based air-pumping model. In the genetic algorithm used in previous studies, there are a number of problems related to the encoding structure and the selection of an objective function. This paper proposes a single encoding element with five integers, a divergent objective function based on an evolutionary process, and the optimal evolutionary rate based on the Shannon entropy in an attempt to solve the problems. The results of the proposed genetic algorithm with an evolutionary process are compared with those of a randomized algorithm. The randomized algorithm is a traditional method used to obtain the tyre pitch sequence. It was confirmed that the genetic algorithm more effectively reduces the peak value of the predicted tyre air-pumping noise. The consistency and cohesion of the obtained simulation results are also improved.

“…It was found that the tread-block-structure form affected its grounding pressure and deformation characteristics, and reasonable control of the tread-block structure can effectively improve the tire grip-performance. Mundl et al [ 8 ] showed that the tread-pattern structure affects the tread stiffness of the tire, thus changing the tire’s grip performance. Therefore, the optimization of the tread-pattern structure can effectively improve the tire grip-performance.…”

To solve the technical problem that wheeled vehicles are prone to skidding on complex ground, due to poor adhesion performance, a tire-tread-structure design method based on the bionic principle is proposed in this paper. The 3D model of a goat’s foot was obtained using reverse engineering technology, and the curve equation was fitted by extracting the contour data of its outer-hoof flap edge, which was applied to the tire-tread-structure design. The bionic and herringbone-pattern rubber samples were manufactured, and a soil-tank test was carried out using an electronic universal tensile-testing machine, in order to verify the simulation results. The results showed that the overall adhesion of the bionic tread-pattern was greater than that of the normal tread-pattern with the same load applied and the same height and angle of the tread-pattern structure, and the maximum adhesion was increased by 14.23%. This research will provide a reference for optimizing the pattern structure and thus improving the passing performance of wheeled vehicles.
